Tumor-Infiltrating Immune Cells and PD-L1 as Prognostic Biomarkers in Primary Esophageal Small Cell Carcinoma

Figure 5

Development of the nomogram for predicting OS in patients with PESCC. To estimate the OS of an individual patient, the value of each factor is acquired on each variable axis, and a straight line is drawn upward to determine the points. The sum of these 4 numbers is located on the total points axis, and then, a line is drawn downward to the survival axes to determine the likelihood of survival.
